VEHICLE JACK.

Application fl1ed 0qtobe r'28, 1924. Serial No. 745,340.

To all whom it may comer-n:

Be it known that I, LEVI E. ENGEL, a citizen of the United-States ofAmerica, and resident of the town of Elbe, in the county of Pierce andState-of Washington, have invented certain new and useful Improvementsin Vehicle Jacks, of which the following is a specification. i

My invention relates to lifting jacks and particularly to jacks intendedfor use in lifting automobiles and like vehicles, as for the purpose ofrepairing and like services.

It has been particularly my purpose to provide a jack suitablefor useabout garages and one capable of being inserted far under cars andattached equipment or loads, one capable of being inserted under partswhich have slight clearance above the ground and one capable of directlymaking a high lift-.

My invention comprises certain combinations of arts which will behereinafter set referred embodiment has been illustrated in the accomanying novel will be defined in the accompanying claims. The drawingsillustrate the principles of my invention asembodied in the specificconstruetion which is. now preferred by me.

. Figure 1 is a side elevation of my improved jack showing it as aplied. to a car. Figure 2 is a side view 0 the jackin its loweredposition, an end of one side beam being broken away.

Figure-3 is a transverse section upon and adjacent to the beam pivot orupon the offset line 3-3 of Figure 2.

The special service for which my ack has been desi ed is the raising ofautomobiles as is so requentl necessary about garages and to enable thlsto be quickly and conveniently done under conditions in which 1 doingthis with the more common types of jacks is diflicult.

This has been done by using two levers or beams pivoted together towardsthe middle of their length and occupying approximately a horizontalposition, one end of these beams being-insertible under the carand theother ends being'separated by a pow'erdevice connected thereto.

The beams 1 and; 2, which are pivoted together at 12, are shown as beingeach made of two rigidly connected bars. While this is desirable for thebeam 1, it is wholly immaterial for the beam'2. The beam 2 for.

drop between the parts of beam 1, as has been indicated in Figure 2.

Thismme end of beam 1 should preferably extend somewhat beyond beam 2,first, to accommodate the shaft 30 of the carrying wheels 3 and, second,to extend the ground bearing point somewhat beyondthe load carrying foot4, thereby keeping the load-well within the base. .At the opposite endthe beam 2'may to advantage be mounted upon a frame '5 having bearingwheels 50, which bearing wheels may also be mounted as castors to turnfreely, as has been illustrated. The device as shown contemplates theuse of three wheels placed in, triangular position. By further using apivot connection 51 of frame with beam 2, a flexible and adjustablesupport is secured. The outer ends of beams 1 and 2 are connected by anysuitable device'for applying power toseparate them. The device showndescription may be Omitted; The casing has a finger or bracket 61 whichreceives a link or clevis 10 carried b beam 1.

The lifting foot 4 shou d at all times be maintained in the same angularposition with relation to the horizontal. To secure.

this it is pivoted 'at' 40 and has a downwardly extending arm 41 towhich is ivoted. a controlling link or links 7 piv atits other end tothe beam 1, that is, to the other of the beams than that to which thefoot 4 is pivoted. Further, the distance. between the pivots of foot 4should be twice that between the pivot 12, between the two beams, andthe pivot point 7 0 where the controlling link 7-is connected with thebeam 1.

With this jack the lifting end may be in-. sorted a considerable,distance under the car and objects carried thereby, and under a parthaving slight clearance. Further, by reason of the length of the beamsland 2, the lift may be carried to a very considerable height. It isconvenient to handle and operate and is stable and firm when in use;

"What I claim as my'invention is:

1. A vehicle jack comprising two pivoted beams, means for applying powerto one end of the beams to separate them, a lifting foot pivoted uponthe other end of one of the beams, and a link pivotally connecting thelifting foot with the other beam to thereby maintain the loot inasubstantially constant angular position relative to a fixed plane.

I '2; A vehicle jack comprising two pivoted beams, means for applyingpower to separate the swinging ends of the beams, a lifting footprovided upon the swinging end of one of the beams, and a link pivotedto the foot below its supporting pivot and to the other beam below thepivot for the two beams.

3. A vehicle jack comprising two pivoted beams, means for applying powerto separate the swinging ends of the beams, a lifting foot provided uponthe swinging end of one of the beams, and a link pivoted by one end tothe :toot below its supporting pivot and to that beam upon which thefoot is not mounted, at a distance below the pivot between the two beamshall that between the foot in a fixed angular position.

5. A vehicle jack comprising a beam, a lifting foot pivoted to one endof said beam, and a lifting mechanism connected with the other end ofthe beam, a second beam composed of two bars located to lie respectivelyat opposite sides of the first-mentioned beam, said beams beingcentrally pivoted together, and a controlling link pivoted to thelifting foot/below its supporting pivot and to the second beam below thepivot between the two beams a distance substantially half that betweenthe supporting pivot of the (ill foot and the connection of the link tothe foot.
